TECHNICAL FIELD

Exemplary embodiments of the present invention relate generally to assemblies for electronic displays.

BACKGROUND AND SUMMARY OF THE INVENTION

Electronic displays have grown in popularity not only for indoor use, but also for outdoor use. One exemplary application, without limitation, is the digital out of home advertising market where the electronic displays are increasingly replacing the use of static posters. The use of electronic displays is advantageous because they allow images to be changed quickly as well as permit the use of videos and interactive displays, among other benefits. Such displays have been placed in many locations, including but not limited, on billboards, the tops of vehicles, bus shelters, kiosks, sidewalks, stadiums, buildings, and the like.

Such outdoor and indoor display assemblies are often placed in areas of public gathering. It is desirable to add peripheral devices to such displays as such peripheral devices include desirable features that draw individuals to the assemblies or may facilitate data gathering regarding individuals near the assemblies. It is desirable to have individuals dwell or linger around the displays, particularly when the displays are showing advertisements, such that the individuals are exposed to additional content. Examples of such peripheral devices include, but are not limited to, cameras, touchscreens, additional screens, charging devices, emergency notification, and the like.

For example, without limitation, as the use of personal electronic devices has increased, the desire for public area charging stations has also increased. Such personal electronic devices need to be periodically recharged, which requires connectivity to a power source and time to allow the personal electronic device to charge. Adding charging devices to a display assembly can increase dwell time near the display assembly. In order to incentivize individuals to spend additional time in view of the display, what is needed is a display that also offers peripheral devices, such as but not limited to, the ability to charge personal electronic devices.

Additionally, these peripheral devices generally require access to an electrical power source and communications network to operate. Such peripheral devices generally comprise sensitive electronics which require particular temperature ranges and operating environments to function properly. As such, it is desirable to provide a substantially sealed, temperature regulated cavity within the assembly for said peripherical devices and their supporting electronic components so as to limit exposure to contaminants and the elements. Each peripheral device, of which there may be many in a single assembly, requires wiring to provide the electrical connection to said power source and communications equipment. Said wiring, however, must generally travel outside of the cavity to connect to the power source and/or communications equipment. Therefore, it is desirable to provide a wire harness that provides electrical connectivity to the peripheral devices by way of a substantially sealed entry point into the cavity. Additionally, the use of a wire harness provides organization and ease of connection/disconnection, particularly when servicing the display assembly.

The present invention is an assembly comprising a display assembly that offers a substantially sealed, temperature controlled cavity for peripheral devices and a substantially sealed entry point into the cavity. For example, without limitation, the assembly may comprise a charging subassembly located on a housing of the assembly. The charging subassembly may comprise various charging adapters that are configured to charge a variety of personal electronic devices. The charging adapters may be wired to a common power source that also powers the display. The charging adapters may extend from any part of the housing of said display assembly.

A wire harness may provide electrical connectivity to the peripheral devices and other components, such as but not limited to the charging subassembly, through an outlet or a pass-through device into the cavity. The wire harness may extend from the common power source and/or communications network along a frame within the housing of the assembly. The wire harness may enter the cavity via a substantially sealed pass-through device or be in electrical connection with a substantially sealed outlet located on the frame. Regardless, the outlet or pass through device may provide electrical connectivity to wiring located inside the cavity configured to provide power to the peripheral devices while substantially sealing the cavity from outside air or contaminants.

The wiring harness may also provide for tidy organization of the wires. It may also serve as a single connection/disconnection point for servicing the display. For example, without limitation, should an entire display assembly or component need replaced, the wire harness may provide a single wiring disconnection and reconnection as part of the removal process and replacement process.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENT(S)

Various embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In the following description, specific details such as detailed configuration and components are merely provided to assist the overall understanding of these embodiments of the present invention. Therefore, it should be apparent to those skilled in the art that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present invention. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

FIG. 1 is a front perspective view of an exemplary assembly 10 in accordance with the present invention. The assembly 10 may comprise one or more display assemblies 14 placed within a housing 6. The housing 6 may comprise a stand 8 for mounting the assembly 10 to the ground. However, in other exemplary embodiments, the assembly 10 may be mounted to another object such as, but not limited to, a bus shelter, a post, a wall, a building, or the like. Regardless, an intake 16 may be located on the top of the housing 6. As will be described in greater detail herein, an exhaust 9 may be located on the bottom of the housing 6. However, it is contemplated that the intake 16 may be located on the bottom of the housing 6 with the exhaust 9 being located on the top of the housing 6.

FIG. 2 is a front perspective of the assembly 10 of FIG. 1 illustrated with the stand 6 removed to illustrate additional components of the assembly 10. The display assemblies 14 may be mounted to a frame 12. The frame 12 may be substantially rectangular in shape and may have interior and exterior surfaces or panels. In exemplary embodiments, the assembly 10 may comprise a single display assembly 14 mounted to the frame 12. In such embodiments, an access panel 48 may be mounted to the opposite side of the frame 12. As will be explained in greater detail herein, in exemplary embodiments the access panel 48 may be configured to receive a static poster. In other exemplary embodiments, the assembly 10 may comprise a first and a second display assembly 14 placed back-to-back on either side of the frame 12. Regardless, the frame 12 may be configured to be connected to the stand 8, another object, or directly to the ground.

As will be explained in greater detail herein, the assembly 10 may further comprise an electronics cavity 18 for storing electronic components 30 for operating the assembly 10. In the exemplary embodiments comprising the single display assembly 14, the electronics cavity 18 may located in the space between the display assembly 14, the frame 12, and the access panel 48. In other exemplary embodiments comprising the first and second display assemblies 14 placed back-to-back, the electronics cavity 18 may be located in the space between the display assemblies 14 and the frame 12. The first and second display assemblies 14 may share a common electronics cavity 18.

Regardless, the intake 16 may likewise extend through the frame 12. Similarly, the exhaust 9 may extend through the frame 12.

FIGS. 1 and 2 illustrate the display assemblies 14 in a closed position such that the display assemblies 14 are in contact with the frame 12 or are located substantially parallel to the ground. As will be explained in greater detail herein, the display assemblies 14 may be hingedly mounted to the frame 12 by way of a hinging device 22. A pair of hinging devices 22 may be located on either side of the frame 12. In the exemplary embodiments comprising the first and second display assemblies 14 located back-to-back, the same hinging devices 22 may be used to hingedly mount the first and the second display assemblies 14 to the frame 12, though such is not required. In exemplary embodiments, the hinging devices 22 may be located on an upper portion of the frame 12, though any location of the hinging devices 22 is contemplated.

FIG. 3 is a front perspective view of the assembly 10 of FIG. 2 illustrated with one of the display assemblies 14 in an open position. The display assembly 14 may rotate via the hinging device 22 into the opened position such that the bottom of the display assembly 14 is swung outwardly away from the frame 12. This may allow access to the electronics cavity 18 such that personnel may inspect, maintain, repair, replace, or otherwise service the electronic components 30 located therein.

The assembly 10 may further comprise a pair of aid devices 20, preferably having a first end and a second end, though such is not required. In exemplary embodiments, the aid devices 20 may be gas springs, though any type of aid device is contemplated. Such aid devices 20 may include, but are not limited to, any device which utilizes a mechanical advantage in order to assist is moving the display assemblies 14 between an open position or closed positions as well as, or alternatively, to temporarily secure the display assemblies 14 in the open position or closed position. Other exemplary aid devices 20 include, but are not limited to, struts, springs, block and tackle, counterweights, levers, gears, tethers, belts, chains, motors, screws, some combination thereof, or the like.

The first end of the aid devices 20 may be mounted to either side of the display assembly 14 and the second end of the aid devices 20 may be mounted to either side of the interior of the frame 12. In exemplary embodiments, the first end of the aid devices 20 is mounted lower relative to second end of the aid devices 20, though the opposite is contemplated. The aid devices 20 may be configured to assist with movement of the display assemblies 14 between the open and the closed positions as well as temporarily securing the display assemblies 14 in the opened or the closed positions.

In exemplary embodiments, the display assemblies 14 may be lockable to the frame 12 or the housing 6 such that the display assemblies 14 cannot normally be moved from the closed position unless unlocked. This may assist in restricting access to the electronics cavity 18 to authorized personnel.

For clarity, in exemplary embodiments where back-to-back display assemblies 14 are used, each of the first and the second display assembly 14 may comprise a first and second aid device 20 such that each of the display assemblies 14 may be moved between, or selectively secure in, the opened and the closed position. In exemplary embodiments where a single display assembly 14 is used, the display assembly 14 may comprise the first and second aid devices 20 such that the display assembly 14 may be moved between, or be selectively secured in, the opened and the closed position. In such embodiments, the access panel 48 may form the rear surface of the assembly 10 and may be swung outwardly and/or upwardly to allow access to the electronics cavity 18 as described in greater detail herein, though any direction of rotation or movement is contemplated.

FIG. 4 is a front perspective view of the assembly 10 of FIG. 2 illustrated with one of the display assemblies 14 removed so as to illustrate the electronics cavity 18. A gasket 28 may extend around the perimeter of either side of the frame 12. In exemplary embodiments where the first and second display assemblies 14 are placed back to back, the gaskets 28 may provide a substantially air tight seal when the display assemblies 14 are placed in the closed position. In exemplary embodiments where a single display assembly 14 is used, the gaskets 28 may provide a substantially air tight seal when the display assembly 14 and the access panel 48 are placed in the closed position. Regardless, this may allow the electronics cavity 18 to be sealed substantially air tight, though such is not required.

A plate 19 may be located in the electronics cavity 18 and the electronic components 30 may be mounted thereto. In exemplary embodiments, the plate 19 may be mounted to the frame 12 such that the plate 19 extends substantially parallel to the front surface of the electronic display assemblies 14 when the electronic display assemblies 14 are located in the closed position. Stated another way, the plate 19 may extend substantially perpendicular to the ground.

The electronic components 30 may comprise any number of components used to operate the assembly 10 and its various components. Such electronic components 30 may include, but are not limited to, power sources, power distribution components, video players, video receiver boards, processors, electronic storage devices, communications equipment, wireless transmitter/receivers, network connectivity devices, printed circuit boards, and the like. In exemplary embodiments, a number of the electronic components 30 may be utilized to operate both display assemblies 14 (in the embodiments where two display assemblies 14 are used). For example, but not to serve as a limitation, at least the video players, video receiver boards, communications equipment, wireless transmitter/receivers, and network connectivity devices may be shared. This may reduce the number of electronic components 30 required. In exemplary embodiments, the plate 19 may be a server rack, though such is not required.

The hinging device 22 may comprise a frame hinge plate 26 and a display hinge plate 24. The frame hinge plate 26 may be located on the exterior panels on either side of an upper portion of the frame 12 such that the frame hinge plate 26 extends substantially perpendicular relative to the plate 19. The frame hinge plate 26 may comprise one or more notches or apertures for mounting the display hinge plate 24 thereto. The display hinge plate 24 may be located on either side of an upper portion of the display assembly 14 such that the display hinge plate 26 extends substantially perpendicular relative to the plate 19. The display hinge plate 24 may comprise one or more notches or apertures corresponding to the notches or apertures located in the frame hinge plate 26. Any number of fasteners 27 may extend through the corresponding notches or apertures in the display hinge plate 24 and the frame hinge plate 26 such that the frame hinge plate 26 may be hingedly secured to the display hinge plate 24. The fasteners 27 may include a threaded fastener, pin, or the like. This is merely exemplary, any type of hinge device 22 is contemplated.

The design of the hinge device 22 may provide for easy removal of one or both of the display assemblies 14 when performing inspections, maintenance, repairs, replacements, or otherwise servicing the assembly 10. The fasteners 27 may simply be removed from either side of the display assembly 14 and the entire display assembly 14 may be removed. A replacement display assembly 14 may then be installed. The display assembly 14 being inspected, maintained, repaired, replaced, or otherwise serviced may then be returned to a service center for servicing. This may minimize downtime of the assembly 10.

FIG. 5 illustrates exemplary flow paths through the assembly 10 of FIG. 4. FIG. 6 illustrates a top sectional view of an exemplary display assembly 14 to further illustrate said exemplary flow paths. Each display assembly 14 may comprise a cover panel 17 that faces an intended viewer. An electronic display 11 may be located behind, spaced apart from, and substantially parallel to the cover panel 17. Cover panel 17 may be comprised of any substantially transparent or translucent material and may be comprised of multiple layers. The electronic display 11 may be any type of electronic display 11, including but not limited to, a liquid crystal display (LCD), light emitting diode (LED) display, organic LED (OLED) display, plasma display, or the like. The space between the rear surface of the cover panel 17 and the front surface of the electronic display 11 may define a first channel 25. A display assembly housing 15 may surround the electronic display 11 such that the combination of the cover panel 17 and the display assembly housing 15 substantially encloses the electronic display 11. One or more of the display assemblies 14 may further configured to receive touch input. For example, without limitation, the electronic display 11 may be a capacitive or resistive touch screen, though any type of touch screen is contemplated.

A backlight 21 may be located behind and substantially parallel to the electronic display 11. The backlight 21 may be spaced apart from the electronic display 11, though such is not required. A second channel 23 may be located within the display assembly 14 and may be configured to receive ambient air 38. The second channel 23 may permit ambient air 38 to flow vertically through the display assembly 14. In exemplary embodiments, the second channel 23 is defined, at least in part, by the space between the rear surface of the backlight 21 and the rear surface of the display assembly housing 15, though any location is contemplated.

A first and a second side channel 32 may extend along either side of the display assembly 14. The side channels 32 may be configured to receive circulating gas 36. In exemplary embodiments, the side channels 32 are defined, at least in part, by the space between the second channel 23 and the side of the display assembly housing 15, though any location is contemplated.

One or both sides of the frame 12 may comprise a side gap 13 located between interior and exterior side panels. As such, the assembly 10 may comprise a first and a second side gap 13, where each is located on either side of the frame 12. In other exemplary embodiments, the assembly 10 may comprise only a first side gap 13. Apertures may be located along the interior panels of the side(s) of the frame 12 having the side gap(s) 13 such that circulating gas 36 may be passed from the electronics cavity 12 into and out of the side gap(s) 13. In exemplary embodiments, the circulating gas 36 may flow from the first side gap 13 though the first side channel 32, though the first channel 25, through the second side channel 32, through the second side gap 13, though the electronics cavity 18, and be returned to the first side gap 13, thereby forming a closed loop. In exemplary embodiments where the assembly 10 comprises only the first side gap 13, the circulating gas 36 may pass directly from the electronics cavity 18 into or out of the first or the second side channel 32. Additionally, in exemplary embodiments where two display assemblies 14 are placed back-to-back, the circulating gas 36 may be split and travel through first channel 25 located in each respective display assembly 14. Side gaps 13 are not required.

One or more fans 34 may be mounted to said apertures in the interior panels of the side of the frame 12 to force the circulating gas 36 though the closed loop, though it is contemplated that any number of fans 34 may be placed at any number of locations along the path of the circulating gas 36.

The bottom and top of the frame 12 may similarly comprise interior and exterior panels with an upper gap 41 and a lower gap 40 located therebetween, though such is not required. Apertures may be located along the exterior panels of the bottom and top of the frame 12 such that ambient air 38 may be ingested from outside of the assembly 10 and exhausted from inside of the assembly 10. These apertures may form the exhaust 9 and the intake 16. In exemplary embodiments, ambient air 38 may be ingested from the bottom of the assembly 10 into the lower gap 40. The ambient air 38 may then travel vertically upwards through the second channel 23 in the display assembly 14 and into the upper gap 41. The ambient air 38 may then be exhausted through the intake 16, thus forming an open loop. In the exemplary embodiments where the first and the second display assemblies 14 are placed back-to-back, the ambient air 38 may be split and travel through each of the channels 23 located in each of the respective display assemblies 14.

One or more fans 34 may be mounted to said apertures in the exterior panels of the bottom of the frame 12 to force the ambient air 38 though the open loop, though it is contemplated that any number of fans 34 may be located in any number of locations along the path of the ambient air 38.

The ambient air 38 flowing through the second channel 23 may be in thermal communication with the backlight 21 so as to absorb heat generated therefrom, though such is not required. The ambient air 38 flowing through the second channel 23 may be in thermal communication with circulating gas 36 flowing through the closed loop such that the relatively cool ambient air 38 may remove heat from the relatively warm circulating gas 36. The ambient air 38 flowing through the open loop may be in thermal communication with the circulating gas 32 flowing through the closed loop so as to absorb heat therefrom while not allowing the ambient air 38 and the circulating gas 32 to substantially mix.

FIG. 7 is a front perspective view similar to FIG. 1 of another exemplary embodiment of the assembly 10 also indicating section lines A-A and B-B.

FIG. 8 is a front perspective view of the assembly 10 of FIG. 7 illustrated with both display assemblies 14 in the open position. The plate 19 may be mounted to one of the display assemblies 14. In other exemplary embodiments, the plate 19 may form a part of the display assembly 14. Many or all of the electronic components 30 may still be shared by the display assemblies 14.

FIG. 9 is a front perspective exploded view of the assembly of FIG. 8. A second plate 42 may be mounted to the frame 12, though such is not required. The second plate 42 may be located an upper portion of the electronics cavity 18, though any location is contemplated. The second plate 42 may be mounted to extend parallel to the front surface of the electronic display assemblies 14 when the electronic display assemblies 14 are in the closed position. The second plate 42 may be configured to receive additional electronic components 44, which may be mounted thereto. In exemplary embodiments, the additional electronic components 44 may comprise customer-specific or customer-installed electronic components or components to operate the assembly 10. However, any type of electronic components 44 are contemplated, such as but not limited to, computers, processors, routers, servers, machine to machine communications equipment, wireless connectivity devices, Bluetooth connectivity devices, near field communication devices, cameras, electronic storage devices, memory, and the like. In exemplary embodiments, the second plate 42 may be a server rack, such as but not limited to, a 1U server rack.

By placing the display assemblies 14 in the opened position, the elections cavity 18, the plate 19, the second plate 42, the related electronic components 30 and additional electronic components 44 may be maintained, repaired, replaced, or otherwise serviced. Additionally, the display assemblies 14 themselves may by maintained, repaired, replaced, or otherwise serviced by removing the display assemblies from the hinging device 22 as previously discussed.

Various pass through devices 35 may be located in the walls defining the cavity 18 such that power lines, communication lines, and the like may be passed into the cavity 18 from outside. The pass-through devices 35 may be configured to provide a substantially air and water tight seal. Any number and location of said pass through devices 35 are contemplated. This may help to reduce the number of pass through points in the assembly 10 and simplify the cabling. The cavity 18 may provide a substantially sealed, cooled, connected, and/or powered electronics cavity 18 for mounting electronic components, such as but not limited to, the additional electronic components 44 and the electronic components 30.

FIG. 9 illustrates an exemplary assembly 10 where the fans 24 for the ambient air 38 may be located on the top of the frame 12 in the apertures of the upper gap 41.

FIG. 10 is a top sectional view taken along section line A-A of FIG. 7 and illustrating the display assemblies 14 in the closed position. The second channel 23 may comprise a corrugation layer 46 located between the backlight 21 and the electronics cavity 18. The ambient air 38 may pass through the corrugation layer 46. As illustrated in FIG. 10, the assembly 10 may only comprise the first side gap 13. It is contemplated that the first side gap 13 may be located on either side of the assembly 10 or may not be required at all.

FIG. 11 is a side sectional view taken along section line B-B of FIG. 7. As illustrated in FIG. 11, the lower gap 40 is optional. Instead, ambient air 38 may enter via the exhaust 9 and be ingested directly into the display assemblies 14 where it may travel through the second channel 23 to the upper gap 41 and exit via the intake 16.

FIG. 12A and FIG. 12B is a rear perspective view of another exemplary assembly 10. FIGS. 12A-12B illustrates an exemplary assembly 10 having a single display assembly 14 and further comprising the access panel 48 located on the rear of the frame 12. The access panel 48 may be a door, though any type of access panel 48 is contemplated. The access panel 48 may be comprised of sheet metal, though any material is contemplated. In other exemplary embodiments, the access panel 48 may be configured to hold a static poster. For example, without limitation, the access panel 48 may comprise a transparent cover located above the door to define a poster cavity configured hold the poster such that it may be located therebetween. In yet another example, without limitation, edge lighting may be placed at various locations around said poster to illuminate the poster.

In exemplary embodiments the access panel 48 may swing open horizontally (as shown in FIG. 12A) or vertically (as shown in FIG. 12B). In exemplary embodiments where the access panel 48 swings open vertically, aid devices 20 may likewise be used to assist in moving the access panel 48 between the open and closed positions as well as securing the access panel 48 in the open and closed positions. The access panel 48 may be lockable to the frame 12 or the housing 6 such that the access panel 48 cannot normally be moved from the closed position unless unlocked. This may assist in restricting access to the electronics cavity 18 to authorized personnel.

In exemplary embodiments, the plate 19 may be mounted to the access panel 48. In still other exemplary embodiments, the access panel 48 may be the plate 19.

Although the flow of the ambient air 38 and the circulating gas 36 may be shown and described herein with respect to particular directions and orientations, it is contemplated that the ambient air 38 and the circulating gas 36 may flow in other directions. For example, without limitation, ambient air 38 and circulating gas 36 shown as flowing clockwise may flow counter-clockwise, when shown flowing vertically from top to bottom may flow from bottom to top, when shown flowing horizontally from right to left may flow from left to right, when shown flowing vertically may flow horizontally, when shown flowing horizontally may flow vertically, and the like.

It is contemplated that the assembly 10, or various components thereof, may be adapted for and/or used with any size display assemblies 14 in any application. For example, but not to serve as a limitation, the assembly 10, or various components thereof, may be adapted for and/or used with a vehicle topper unit such as is illustrated and described in U.S. patent application Ser. No. 15/450,365 filed Mar. 6, 2017, the disclosures of which are hereby incorporated by reference in their entirety.

FIG. 13 is a front perspective view of another exemplary assembly 100 also indicating Detail A. FIG. 13 through FIG. 18B illustrate and describe an adaptation of the assembly 10 for use with a vehicle topper unit as previously mentioned. Similar features have been similarly numbered but increased by 100 (e.g., assembly 10 and assembly 100). The assembly 100 may comprise a frame 112 which may be rectangular in shape, though any shape is contemplated. The frame 112 may be covered by cladding that forms a housing. The cladding may provide an aesthetically pleasing appearance and may improve aerodynamics. The frame 112 may be adapted to be mounted to the roof of a vehicle, though such is not required. A first and second display assembly 114 may be attached to the frame 112, though any number of display assemblies 114 are contemplated. In exemplary embodiments, the first and second display assemblies 114 are placed back-to-back on either side of the frame 112. The assembly 100 may further comprise a pair of mounting devices 150. In exemplary embodiments, the mounting devices 150 may be located on the underside of the frame 112 and may be feet configured to permit the assembly 100 to be mounted to the roof of a vehicle, though any type of mounting device 150 is contemplated.

A fan 134 may be located on an aperture in the frame 112 to permit the ingestion of ambient air 138. Once ingested, the ambient air 138 may travel horizontally through channels in the display assemblies 114 and exit through apertures on the other end of the frame 112. This may form an open loop. It is contemplated that the fan 134 may be located at any location along the path of the ambient air 138.

FIG. 14 is a front perspective view of the assembly 100 of FIG. 13 illustrated with one of the display assemblies 114 in the open position. The display assemblies 114 may be hingedly mounted to the frame 112 by way of a hinging device 122. The hinging device 122 may permit the display assemblies 114 to be moved between a closed position, wherein the respective display assembly 114 rests against the frame 112 and/or where the front surface of the respective display assembly 114 is substantially perpendicular to the ground, and an open position wherein the respective display assembly 114 is rotated outwardly from the frame 112 and/or where the front surface of the respective display assembly 114 is substantially parallel to the ground.
